When is it necessary to start a new period in the periodic table?
Periods in the periodic table represent the number of electron shells necessary to fit all of the electrons. Once you fill the valence shell of an atom, the next electron must go in a new electron shell. This would constitute a new period on the periodic table.
Does noble gases fill more that one column of the periodic table?
No. The noble gasses take up a single column of the periodic table
The importance of periodic table-of-elements?
u can easily apply the knowledge of periodic table say, atomic weights, atomic numbers, no. of protons or electrons, no. of neutrons, many more to fill the s,p,d,f shells, to identify an element when it's group or period number is given through 2,8,8,18,18,32 method
Explain how information about an element's physical state at room temperature will help you fill in the partial periodic table?
Explain how information about an element's physical state at room temperature will help you fill in the partial periodic table.
Why is He over Ne in the periodic table?
The number of protons in the nucleus increases as you go to the right or go down in the periodic table. Elements of the same period exhibit common characteristics and are placed in the same column. In this case, both helium (He) and neon (Ne) are "noble gases", i.e. they have full electron shells and are extremely unreactive; noble gases do not even form diatomic molecules like some of their neighbors in the periodic chart like oxygen and chlorine. The first electron shell to fill is the 1s shell, which fills with 2 electrons. Helium, with two protons in its nucleus is the first element to have a full shell. It thus sits at the top of the table. The next orbitals to fill are the 2s and 2p which require 2 and 6 electrons respectively. Neon, with 10 protons in its shell is the first element to fill both these shells and this sits immediately below helium in the table.
Where are atoms with fuller electron shells located on the periodic table?
If by 'fuller' you mean a larger number of electrons or a larger number of shells then theoretically the closer to the bottom and right of the the table the 'fuller' the atom would be. However because the periodic table doesn't tell you the number of electrons simply the number of protons and because atoms of the same ilk can vary largely due to a massive number of variables this would be more representative of possible 'fullness'. If by 'fuller' you mean the material as whole that tends to fill it's potential for electrons(and therefore shells) it would be the noble gasses(far right hand side radon and up) because they are the most stable. If you meant 'Where are atoms with fuller electron shells located on MY PARTICULAR COPY of the periodic table" I don't know. That thing has like a quintillion atoms, I would guess somewhere around ununbium.
What are the empty spaces in the periodic table meant for?
It was recognized by the inventor of the Periodic table that these empty spaces are for elements/isotopes that would be discovered someday. Dmitri Mendeleev is generally credited with the publication, in 1869, of the first widely recognized periodic table. He developed his table to illustrate periodic trends in the properties of the then-known elements. Mendeleev also predicted some properties of then-unknown elements that would be expected to fill gaps in this table.
What is the modern name for eka-silicon?
Ekasilicon is germanium['eka' is Sanskrit language for: 'first' place down under Si)Germanium was isolated in 1886, and provided the best confirmed prediction of Mendeleev's periodic table, which was built up before the discovery of Ge.(Professor Dmitri Mendeleev published the first Periodic Table of the Atomic Elements in 1869).When he proposed his periodic table, he noted some gaps in the table, and predicted that as-of-yet unknown elements existed with properties appropriate to fill those gaps.
The element silicon has been omitted from this table. It appears in Period 3 of the periodic table betweenaluminum and phosphorus. Given that information, which of the five columns in the chart could you fill in forsilicon?

Draw an atom use periodic table to fill in the information need to make a model of the element aluminum?
Sorry. Cannot draw on Wiki.
Why is neon in the same group as helium in the periodic table?
Neon and hydrogen are not in the same group in the periodic table. Perhaps you meant neon and helium, which are in the same group. ------------------------------------- And if you did mean Helium and not Hydrogen, then Helium and Neon are in the same group because the group they are in are all elements with "full" electron shells.
Can nonmetals gain electrons to fill their valence shells?
Yes, nonmetals generally gain electrons to fill valence shells.
